A percent is a number compared to 100 (similar to a number compared to a whole or total amount). The total number of questions in this problem would be the number he got right plus the number he missed.
Total number of questions = 7 + 63 = 70 total questions.
That means that he got 7 out of 70 correct.
Now we have to determine what percent 7 out of 70 represents:
7 is equivalent to 1 and 1 is equivalent to 10 .
70 10 10 100
10 in percent form is 10%. He got 10% of the questions right.
100
